Personally you can keep your brass since it dings easily, keep your leather because it'll swell and shrink and unless it's maintained well get dry. Leave you're wood on the tree, and your animal parts on with the animal they both need them and are more attractive there. I'd prefer a wider tip and a more obtuse angles on the edge because my knife is more than a knife and I don't want it to chip easily. I don't want uber hard steels because I can sharpen but I don't want to spend lots of time doing it. It's 2018 I want bauhaus with modern materials since I don't long for the "good ole' days".
